Abstract: 406,376. Ticket-printing apparatus. LAW, H. G., 6, Penn Road, London, and LAW, R. H., 15, Lexden Road, Mitcham, Surrey. Sept. 1, 1932, No. 22079. [Class 106 (iii).] Ticket - printing apparatus comprises means for printing on an inserted fare ticket a stage destination symbol which means is automatically set on the setting of fare printing means; means are also provided for varying the stage destination symbol for a given fare according to the type of ticket, e.g. ordinary, child's, workman's, &c. The annular rotatable device 8 which may be an arc of a circle bearing fare symbols for printing on an inserted ticket 4 is set by the finger piece 5 to position a fare symbol 8<a> opposite the printing plate 15 with invariable type. The device 8 is mounted on a ball race or other bearing, the device 8 being positioned by observing indications on it through the window 7. The finger piece is attached to the member 8, is located in its various positions in notches and is shaped so that it extends in a radial direction through a circumferential slot 11 in a boss 12 of the front wall of the casing 1. A disc 21 bearing type indicative of kind of ticket, e.g. ordinary, child's, workman's, &c., is fixed to a spindle 21b rotated by a setting knob 21<a>. The spindle 21b carries a vertical dog 24 which when the spindle 21<b> is rotated will successively engage and urge outwards four radial locking pins 25 to lock one or other of the gear wheels O, R, W, C, normally loose on the sleeve 23, to the sleeve 23 integral with the gear wheel 23<a> engaging with teeth 8<b> on the inner edge of the member 8. The gear wheels O, R, W, C engage respectively with different ratio speed gears O<1>, R<1>, W<1>, C<1> driving the spindle 20b carrying the destination stage printing disc 20 which is thus variably set from the setting of the fare printing member 8 according to the kind of ticket printed by the member 21. A date marker 18, vehicle number plate 48, boarding stage marker 17 set by button 17<a>, and ticket numbering device 16 actuated at each operation of the platen 19 by finger piece 6 are also provided, the markers 16, 17 comprising case-hardened steel discs according to the Provisional Specification. The fare printing member 8 includes a cancelling type marker 8<c> for obliterating the price indication of surrendered " return tickets. The platen 19 is moved towards and away from the printing plane by the rotation of an eccentric 30 through a finger piece 6 fixed to the free end of an arm 32 slotted longitudually to receive a pin 30<c> on the eccentric 30. An inking ribbon 26 is automatically fed from spool 27 to spool 28, a ratchet 28<a> on the spool 28 engaging with a spring finger or pawl 34 reciprocated from an eccentric 35 on the end of a spindle 36 carrying the eccentric 30. A total cash counter 37 is actuated proportionally to the rotation of the fare printing member 8. Counters 38 are individually selectively operated according to the fare value to which the printing member 8 is set. The appropriate counter is actuated by an L-shaped finger 43, spring loaded radially in the member 8, being positioned opposite the pertinent L-shaped lever 39 connected to the corresponding counter 38 by link 41, the finger 43 being depressed on the depression of an arcuate band 44, supported by springs 45, by means of the pin 6<a> on the finger piece 6. In the case of a large number of fare values two rows of counters 38, Fig. 4, are provided, staggered relatively to each other, two L-shaped fingers 43 also being provided. The counters 37 and 38 can be viewed through openings 46 in the base of the casing 1. A record strip 47 is fed across the printing plane at each return movement of the finger piece 6 in a manner similar to that for feeding the inking ribbon 26, the strip 47 being marked by the side of the ribbon opposite to that which marks the ticket, and the strip 47 being carried between the inking ribbon and the member 8 and being of thin material which will not interfere with the marking of the ticket.
